Investigating Hackers on Facebook Application using FRAppE

There are millions of people who install the facebook application and third party apps are always the major problem for fame and addictiveness of Facebook. Thus hackers have known the strength of the apps for spreading the unwanted things. We have found that 15% of apps are malicious. Thus for the problem we have developed our contribution ....i.e. FRAppE (Facebook Rigorous Application Evaluator).FRAppE is to focus on the investigation of malicious apps on facebook.The behavioral sense of 111k Facebook apps in 2.6 million users were used to develop FRAppE. With 99.5% accuracy FRAppE can detect malicious apps with no false positives and a low false negative rate (4.1%).We have a group of features to identify the spam app from good apps. For app testing and ranking we see FRAppE as a step towards creating an independent watchdog that warn users on Facebook before installing apps.
